Asking your audience toaccept controversial premises and conclusions
a. Slippery slope
b. Burden of proof
c. Appeal to ignorance
d. Begging to question

A: slippery slope (http://en.wikipedia.org/wiki/Slippery_slope)
b: burden of proof (http://en.wikipedia.org/wiki/Burden_of_proof)
c: Appeal to ignorance (http://en.wikipedia.org/wiki/Argument_from_ignorance)
d: Begging to question (http://en.wikipedia.org/wiki/Begging_the_question)


My guess would be d... Begging to question
because:

"In contemporary usage, "begging the question" often refers to an argument where the premises are as questionable as the conclusion."

Hello Tracy

Wikipedia (http://en.wikipedia.org/wiki/Rhetorical_device) : In rhetoric, a rhetorical device or resource of language is a technique that an author or speaker uses to evoke an emotional response in the audience (the reader(s) or listener(s)). These emotional responses are central to the meaning of the work or speech, and should also get the audience's attention.

Also here select what you FEEL to suit this effect the best.

Success !

:)
